Specification of Letters Patent.

Patented March 9, 1909.

Application filed March 16, 1908. Serial No. 421,449.

Cambri a and State of Pennsylvania, have invented certain new and usefulImprovements in Rails, of which the following is a specification.

My invention relates to certain new and useful improvements in rails forrailways and the like and it particularly seeks to provide a continuousrail having a scarf joint to eliminate the use of fi'sh plates, railchairs, splice bars and the like.

Generically my invention embodies a rail having one end provided with adove-tailed groove in the rail base, a depression in one side of theweb, a beveled portion in the other side of the web, and a beveled andshouldered portion on the end of the rail tread, the adjacent end of thenext succeeding rail section being formed with corresponding butopposite portions to receive those of the preceding rail ends.

In its more specific nature, the invention comprises certainnoveldetails of construction, combination and arrangement of parts, all ofwhich will be first described in detail and then be specifically pointedout in the appended claims, reference being had to the accompanyingdrawings, in which: 4

Figure 1, is a perspective view of a rail embodying my invention lookingat the same from one side. Fig. 2, is a similar view looking at the railfrom the opposite side. Fig. 3, is a detail perspective view of one railendv Fig. 4, is a similar view of the other rail end. Fig. 5, is avertical cross section on the line 55 of Fig. 1. Fig. 6, is a horizontalsection on the line 66 of Fig.

Referring now to the accompanying drawings in which like numerals andletters of reference indicate like parts in all of the figures, 1designates the first rail section and 10 the second rail section, whichrail sections are provided with tread portions 1'10* respectively, a webportion 1"1O respectively and a base portion 1 1() C respectively.

The base portion 1 of the rail section 1 is provided centrally with adove-tailed recess 2 whose side wal s 2 converge slightly upwardlytoward the rail web 1 and the rail web 1 has one side cut away as at 3to form a recess or socket portion to cooperate with and receive thetongue portion 11, of the other rail web 10", the tongue 11 being formedby socketing the web as at: 13 to receive the tongue portion 1 of theweb 1 of the first rail section.

The recess wall 3 of the web 1 extends parallel to the edge 2 of thedove-tailed recess 2, the corresponding face of the tongue 11 lyingcorrespondingly; In other words,

the adjacent faces of the tongues 11' and 1 each lie in contact with oneanother when the rail ends abut while in a plane at an an le to thevertical plane of the rail, as a who e, as clearly indicated in Fig. 6of the drawings.

The web 1 has its tongue end 1 provided with a beveled face 4 wlnchslopes upwardly and lies in a plane at an angle to the vertical plane ofthe rail so as to cooperate withthe undercut face 14 of. the railsection 10 to e interprojecttherewith.

The tread portion 1 of the rail is provided with a face 5 that extendsat an angle of approximately 45 to the vertical plane .of the rail.which makes a right angle with the horizontal but is slightly slantedinwardly to correspond with the correspondingly but oppositely formedface 15 on the tread portion 10 of the other rail section 10, the faces5 and 15 terminating in transverse portions 5--5 and 15*15 res ectively.

The web 1 of the rail section 1 has its under face provided with agroove 1 to project into the grooves 10 of the dove-tail 12 in the faceportion 10 of the section 10.

The ends 1 of the rail section 1 are slightly rounded to cooperate withthe rounded ortions -1 0 of the other rail section so that the partswill all interlock when the rail ends are jointed.

By providing the groove 10 and permitting the rail web tongues 1 to resttherein, a firmsupport is provided for the end of the web 1 and byproviding the cut-away portion 13 to receive the end 1 of the web 1 andby providing the beveled surfaces 4 and the corresponding cut surfaces14 the rail web 10* Will have a bearing on the rail web section 1 andform a support therefor. The beveled surfaces 5 and 15 prevent the carrails binding as they pass over the joint and by virtue of the variousinterlocking tongues and grooves of the rail ends a perfectly solidconnection is made between the rail ends, thus giving a smooth treadsurface to the rails and preventing pounding as the wheels pass over theendsof the rails. Furthermore by providing the dove-tailed interlock-The face 5 does not lie in a plane eliminating the use of splice bars,

ing ton -ue and grooves in the rail bases the rails w' 1 not pull apartlongitudinally.

In assembling the rail ends the rail section 10 has the dove-tailedportion fitted into the dove-tailed groove of the rail section 1 whilethe rail 10 is inclined to the horizontal and is then swun up into ahorizontal position when the ra' ends will be in their -finalinterlocked position.

The rails may be secured to theties by spikes in the usual manner or inany other approved manner and no further connection between the railends will be needed thus rail chairs and the like.

From the foregoing description taken in connection with the accompanyingdrawings,

it is thought the completeconstruction, op-

. eration and many advantages of my invention will be readily understoodby those skilled in the art to which the invention a pertains, and Idesire to say that slig t:

changes in the detail construction, combination and arrangement of artsmay be made Without departing from t e spirit of the invention or thescope of the appended claims.

What I claim is: v

1.. In a rail joint, the combination of a pair.

ofrails each having a'face, a web and a tread portion, one of said railshavin the end of the tread ortion rovided with a beveled face 5 andaving t e web end provided with a beveled face 4, and a groovel on theunder face of the web, said rail end having a dove-tailed recess in thebase, the other rail having a dove-tailed portion to fit said dovetailedrecess and having other portions to cooperate with the beveled faces andunderface o the web of the first rail section.

2. A rail composed of sections, each havin a base, a web, and a treadportion, one of said sections being provided with a beveled face 5 onthe tread portion, a beveled face 4 on the web portion merging with thebeveled face 5, adove-tailed groove 2 in the base porl 1 tion and abeveled face 3 on the web portion 1 face 15 to cooperate with the face 5of thelfirst rail section, the second rail section hav- 5 ing adove-tailed-portion 12 to cooperate with l the dove-tailed groove of thefirst rail section, and having a groove 1O to receive the PTO-f 1jecting portion of the web of the first rail sec- 3. A rail composed ofsections, one of said sections having 1 base at the end of the'rail, theother section -a dove-tailedlreeess' in-the having a dove-tailed portionin the base at i the end of the rail to cooperate with said dove-tailedrecess, the ends-of the rail webs i-each having cutaway portionsoverlappingi one another with the overlapping portion of one'rail webresting in the cutaway ortion of the other-rail web, each of said rashaving tical longitudinal plane of the rail.
